Abstract

The filter element has a filter frame (11) with filter material (12) fitted in it. The filter frame is divided into two part frames (111, 112), which are movably connected along one frame edge by a film hinge (14). This connection is airtight. The film hinge may be made in one with the part frames, or may be connected to them by injection molding.

Description

Die Erfindung betrifft ein Filterelement zum Einbau in eine Belüftungsvorrichtung für Fahrzeuge gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a filter element for installation in a ventilation device for vehicles according to the preamble of claim 1

Solche Filterelemente dienen der Filterung der dem Fahrzeuginnenraum zugeführten Luft und sind als Staubfilter, Kohleaktivfilter oder sog. Kombifilter konzipiert. Sie werden auswechselbar in einem in der Belüftungsvorrichtung integrierten Filtergehäuse aufgenommen.Such filter elements serve the Filtering the air supplied to the vehicle interior and acting as a dust filter, Charcoal filter or so-called combination filter designed. They become interchangeable in one in the aeration device integrated filter housing added.

Bei einem bekannten Filterelement dieser Art ( DE 198 55 244C2 ) ist das Filtermaterial ein Vliesstoff, der zu einem Faltenpack gefaltet und in dem aus Polypropylen gefertigten Filterrahmen aufgenommen ist. Zur Abdichtung des Bereichs zwischen Filterrahmen und Filtergehäuse ist am Filterrahmen stirnseitig eine Doppeldichtlippe angeordnet, die um ein filmscharnierartig ausgebildetes Gelenk schwenkbar ist und sich mit der einen Dichtlippe an eine Faltenwand und mit der anderen Dichtlippe an eine der Faltenwand zugekehrte Begrenzungswand des Filtergehäuses dichtend anlegt.In a known filter element of this type ( DE 198 55 244C2 ), the filter material is a nonwoven fabric which is folded into a fold pack and received in the filter frame made of polypropylene. To seal the area between the filter frame and filter housing, a double sealing lip is arranged on the front side of the filter frame, which is pivotable about a hinge formed hinge-like and with the one sealing lip to a pleated wall and with the other sealing lip on one of the pleated wall facing boundary wall of the filter housing sealingly applies.

Der Erfindung liegt die Aufgabe zugrunde, ein Filterelement der eingangs genannten Art für einen einfachen, montagefreundlichen Filterwechsel in Kompaktfahrzeugen mit engem Einbauraum im Fahrzeugvorbau zu gestalten.The invention is based on the object Filter element of the type mentioned for a simple, easy to install Filter change in compact vehicles with a narrow installation space in the vehicle stem to design.

Die Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the features of claim 1 solved.

Das erfindungsgemäße Filterelement hat den Vorteil, daß durch die Aufteilung der erforderlichen Filterfläche in zwei Teilflächen, die in schwenkbeweglich und luftdicht miteinander verbundenen Filterteilrahmen angeordnet sind, das Wechseln des Filterelements im Filtergehäuse, insbesondere bei beengten Einbauverhältnissen, wesentlich erleichtert wird. Darüber hinaus eröffnet sich die Möglichkeit, das Filtergehäuse in Anpassung an den zur Verfügung stehenden Einbauraum sehr kompakt gestalten zu können, ohne den Luftdurchsatz durch das Filterelement verringern zu müssen.The filter element according to the invention has the advantage that by the division of the required filter surface into two sub-areas, the in pivotable and airtight interconnected filter subframe are arranged, changing the filter element in the filter housing, in particular in cramped installation conditions, much easier. About that opened out the opportunity, the filter housing in adaptation to the available standing installation space very compact, without the air flow to reduce through the filter element.

Vorteilhafte Ausführungsformen des erfindungsgemäßen Filterelements mit zweckmäßigen Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen angegeben.Advantageous embodiments of the filter element according to the invention with appropriate training and embodiments of the invention are set forth in the further claims.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im folgenden näher beschrieben. Dabei zeigt die Zeichnung eine Querschnitt eines Filterelements in schematisierter Darstellung.The invention is based on a in the drawing illustrated embodiment closer in the following described. The drawing shows a cross section of a filter element in a schematic representation.

Das in 1 im Querschnitt skizzierte Filterelement dient zum Einbau in eine Belüftungsvorrichtung für Fahrzeuge. Es wird auswechselbar in ein Filtergehäuse eingesetzt, das in der Belüftungsvorrichtung integriert ist und von dem dem Fahrzeuginnenraum zugeführten Luftstrom durchströmt wird. Das Filterelement kann dabei als Staubfilter oder als Schadstofffilter ausgeführt sein. In einigen Fällen ist auch die Ausbildung als Kombifilter möglich, das eine Aktivkohleschicht für die Schadstoffeliminierung enthält.This in 1 in cross-section sketched filter element is used for installation in a ventilation device for vehicles. It is interchangeable inserted into a filter housing, which is integrated in the ventilation device and is flowed through by the air supplied to the vehicle interior. The filter element can be designed as a dust filter or as a pollutant filter. In some cases, the training as a combination filter is possible, which contains an activated carbon layer for pollutant removal.

Das Filterelement weist einen aus Kunststoff gefertigten Filterrahmen 11 auf, der in dem Filtergehäuse auswechselbar festlegbar ist. Der Filterrahmen 11 ist mit Filtermaterial 12 ausgefüllt, das üblicherweise ein Vliesstoff ist, das in gefalteter Form in den Filterrahmen 11 eingeklebt oder in Form von Materiallagen in den Filterrahmen 11 eingedrückt wird. Der Filterrahmen 11 besitzt zwei größere Hauptabmaße (Länge und Breite) und ein kleineres Hauptabmaß (Tiefe oder Höhe), wobei der Filterrahmen 11 in Einbaulage im Filtergehäuse längs des kleineren Hauptabmaßes durchströmt wird. Die Strömungsrichtung der Luft ist in der Zeichnung durch Strömungspfeile 13 symbolisiert.The filter element has a filter frame made of plastic 11 on, which is interchangeable fixable in the filter housing. The filter frame 11 is with filter material 12 which is usually a nonwoven fabric folded into the filter frame 11 glued or in the form of material layers in the filter frame 11 is pressed. The filter frame 11 has two major main dimensions (length and width) and a smaller main dimension (depth or height), with the filter frame 11 in installation position in the filter housing along the smaller Hauptabmaßes flows through. The flow direction of the air is in the drawing by flow arrows 13 symbolizes.

Der Filterrahmen 11 ist in zwei Teilrahmen 111 und 112 aufgeteilt, die jeweils einen Teil des Filtermaterials 12 aufnehmen. Die beiden Teilrahmen 111, 112 sind längs einer Rahmenkante, die im Ausführungsbeispiel die über die Länge des Filterrahmens 11 sich erstreckende Rahmenkante ist, beweglich und dicht miteinander verbunden. Diese bewegliche und luftdichte Verbindung zwischen den beiden Filterrahmen 11 wird beim Spritzen des Filterrahmens 11 als sog. Filmscharnier 14 mit angespritzt.The filter frame 11 is in two subframes 111 and 112 split, each one part of the filter material 12 take up. The two subframes 111 . 112 are along a frame edge, which in the embodiment over the length of the filter frame 11 extending frame edge is movable and tightly interconnected. This movable and airtight connection between the two filter frames 11 will when spraying the filter frame 11 as so-called film hinge 14 with molded.

Durch die über das Filmscharnier 14 erreichte Knickbarkeit des Filterrahmens 11 kann beispielsweise das Filterelement besser in die Gehäuseöffnung des Filtergehäuses eingesetzt werden. Auch ist es möglich, das Filtergehäuse aus Gründen des beengten Einbauraums nicht mit einer ebenen Gehäuseöffnung zu versehen, sondern mit einer Gehäuseöffnung auszuführen, die zwei zueinander abgewinkelte Ebenen aufweist, wie dies in der Zeichnung dargestellt ist.Through the over the film hinge 14 reached kinkability of the filter frame 11 For example, the filter element can be better used in the housing opening of the filter housing. It is also possible not to provide the filter housing for reasons of cramped installation space with a flat housing opening, but to perform with a housing opening having two mutually angled planes, as shown in the drawing.
